1 Claim.

This invention relates to a package of butter and the method of assembling the package.

The object of this invention is to provide a sanitary container that is inexpensive to manufacture, that is easily assembled, and that will preserve the .shape of the bar or bars of butter. A further object' of the invention is to provide an air and moisture proof Wrapper that can be easily sealed to make a package that is air tight A further objecty of the invention is to make a package that is inexpensive, has an attractive appearance and can be easily. opened when the contents are to be used.y 1 15 A further object of the invention is themethod of making a sanitary package of butter. Referring to the drawing: Fig. 1 is a view of the package partly unwrapped.

l so Flg2 is a perspective view of the iller or protective strip.

Fig. 3 is a conventional bar or print of butter -wrapped in parchment. v j

Fig. 4 is a rectangular block of four one-quarter 25' barst of butter individually wrapped in jparchmen v Fig. 5 is a perspective view of the sealed pack- A age disclosing the overlapping seam.

Fig. 6 is a sectional view on the line 6-6 of Fig.

'30 5, as applied t'o a 'singlebar oi! butter.

The improved package comprises a waterproof or wax wrapper III of suilicient width to extend around the sides o f a bar of butter I I, and to overlap upon one side of the bar. This wrapper. may

35 be used for wrapping the conventional rectangular bar of butter, or to wrap four one-quarter pound bars I2, I3, I4, I5 stacked in a rectangular block. A filler or protecting strip having a body I6, and two end portions I'I is provided to cover 40 one side and the two ends of the bar, or tocover one side and the two ends of the rectangular or prism shaped block formed by stacking four one- `quarter pound bars. The iiller may be made ofv heavy paper stock and is coated or impregnated 45 with wax. The filler I6, I'l serves to preserve the shape of the package and also' protects the butter from the heat that I apply in sealing the wrapper.

If desired the iller I6, Il may be omitted. When the iiller is omitted care must be exercised not to apply excessive heat in sealing the package, and care. must also be exercised so the small wrapped bars do not shift with relation to each other. 5

In assembling the package, theller or protecting strip is placed upon the top andthe two ends of the bar of butter wrapped in parchment or other light wrapper. This assemblage is then wrapped in the waterproof wrapper with the edges 10 I8, I9 overlapping to form the seam 20 over the ller strip. Heat is then applied to the seam at the side and at the ends of the bar to cause the overlapping edges to cohere. This forms a sanitary sealed package that excludes air and moisture, and that tends to preserve the butter. The

heat may be applied with a hot iron or with' any other heating element. This invention provides for packaging butter in neat, rigid, inexpensive, and sanitary packages. g Obviously those skilled in the art to which this A invention pertains may make various changes in the forms of the invention illustrated in the drawing without departingfrom the spirit of this inventgion, and therefore I do not wish to be limited except as set forth hereinafter in the appended claim.

The method of packaging a plurality of bars of butter stacked in a rectangular block which com- 30 prises placing a relatively heavy, unitary protecting strip on one side and the ends of the stack only, wrapping the stacked bars and the protecting strip in a. continuous sheet wrapper ofrelatively light impervious material having wax thereon, to form a seam along said side and said ends only, the seam extending over the said protecting strip, and' applying a heating element along said side and end seams to cause the said overlapping edges of the seam to cohere to form 40 an air tight and moisture resistant ,sanitary package at low cost and having an attractive appearance, the protecting strip being sufficiently heavy to protect the butter from the heat applied in making an air excluding seal.
